Question

Solve for s. 1/2 s = 7/2. A 1/7. B 2/7. C 3. D 7.

Answer 1

The answer is D. 7

Multiply both sides by 2

2*(1/2 s) = 2*(7/2)

s = 7

Answer 2

Simple equation and only requires one step to solve. Remember, a number and a variable juxtaposed means multiplications.

`(1)/(2) s = (7)/(2) \\ \\(((1)/(2)s))/((1)/(2)) = ((7)/(2))/((1)/(2)) \\ \\\\s = ((7)/(2))/((1)/(2)) \\ \\\\s = (7)/(2) * (2)/(1) \\ \\\\s = 7`

One step? I know. It seems more because I was slowing down the calculations for you so could understand everything happening. For someone who can do this in their sleep it would, for them, take one step.
